What does enable NetBIOS over TCP IP do?
NetBIOS over TCP/IP provides the NetBIOS programming interface over the TCP/IP protocol. It extends the reach of NetBIOS client and server programs to the wide area network (WAN). It also provides interoperability with various other operating systems.
Do I need NetBIOS over Tcpip enabled?
A. Yes. To improve performance, it’s recommended that you disable NetBIOS over TCP/IP on your cluster network NIC and other dedicated-purpose NICs, such as for iSCSI and Live Migration. NetBIOS isn’t used in Server 2008 R2 clusters.
What happens if NetBIOS is disabled?
It’s important for an administrator to determine if NBT is in use on the network, understand how to disable its use, and the implications of disabling. For example, disabling NetBIOS can break functionality for some processes if fully qualified domain names are not being used.
How do I force NetBIOS over TCP IP?
Right-click on Local Area Connection and select Properties. Click Internet Protocol (TCP/IP) and select Properties. Click Advanced > WINS. From the NetBIOS setting area, ensure that Default or Enable NetBIOS over TCP/IP are selected.
Why would you want to disable NetBIOS?
NetBIOS was initially created to allow applications to communicate without understanding the details of the network, including error recovery. It operates at the session layer, layer 5 of the OSI model. As with other legacy technologies, the main reason for disabling NetBIOS is security.
Why should be disable NetBIOS over TCP IP?
It is also recommended to disable NetBIOS over TCP/IP to improve network performance. Disabling NetBIOS over TCP/IP is especially recommended on Hyper-V and Windows Server cluster hosts with dedicated NICs used for traffic, such as iSCSI and Live Migration.
What NetBIOS is used for?
NetBIOS (Network Basic Input/Output System) is a network service that enables applications on different computers to communicate with each other across a local area network (LAN). It was developed in the 1980s for use on early, IBM-developed PC networks.
Is NetBIOS over Tcpip safe?
Running NetBIOS over TCP/IP on your corporate network and then connecting your network to the Internet is one of the most dangerous things you can do with a Microsoft-based network. When you run NetBIOS over TCP/IP, you open all your print, file, and application sharing services to any system that can run TCP/IP.
Is NetBIOS enabled by default?
NetBIOS or Network Basic Input/Output System is an API used in Windows when DNS is not available. Even when it runs, it runs over TCP/IP. It’s a fallback method, and it’s not enabled by default.
How do I enable NetBIOS on my NIC?
